Leaky faucet repair in Kingston usually comes down to one worn part, not a full fixture replacement. If your kitchen or bathroom tap in Williamsville keeps dripping after you turn the handle tight, this guide will help you diagnose the cause and make a repair that actually holds.
A small drip is easy to ignore, but it can waste more water than most homeowners expect. The U.S. EPA WaterSense program notes that a faucet dripping once per second can waste more than 11,000 litres per year. That is water you pay for, plus extra wear on the fixture.
The good news is that many faucet drips are safe to check yourself, as long as the shutoff valves work and you move slowly.
Start by Finding Where the Faucet Is Leaking
Before you take anything apart, watch the faucet for a full minute. The location of the water tells you which part has likely failed.
A cartridge is the replaceable internal valve that controls water flow and temperature. An O-ring is a small rubber sealing ring. A valve seat is the metal surface the washer or cartridge seals against.
| Where you see water | Likely cause | First thing to check |
|---|---|---|
| Drip from the spout | Worn washer, cartridge, ceramic disc, or valve seat | Faucet type and internal cartridge |
| Water around the handle | Worn O-ring or packing seal | Handle assembly and retaining nut |
| Water at the base of the faucet | Failed base gasket or loose mounting hardware | Sink deck and faucet body |
| Water under the cabinet | Supply line, shutoff valve, or faucet connection leak | Under-sink connections before faucet parts |
If water is dripping from the spout, you are usually dealing with an internal sealing part. If water is under the sink, stop and inspect the supply lines first. A supply line is the small flexible pipe that brings hot or cold water to the faucet.
Why does my faucet still drip after I tighten the handle?
Tightening the handle does not repair the seal inside the faucet. It only presses harder on a part that may already be cracked, flattened, or coated with mineral buildup. If you keep forcing the handle, you can damage the stem or cartridge and turn a small repair into a larger one.
Leaky Faucet Repair Steps That Actually Stop the Drip
Set out a towel, adjustable wrench, screwdriver, Allen key, needle-nose pliers, plumber’s grease, and a small container for screws. Plumber’s grease is a faucet-safe lubricant used on rubber seals so they do not twist or tear during reassembly.
Follow these steps in order. Do not skip the shutoff test, especially in older Kingston homes where valves may be stiff.
- Clear the cabinet and test the shutoff valves: Turn the hot and cold shutoff valves under the sink clockwise until they stop, then open the faucet to confirm water has stopped flowing.
- If the shutoffs do not work, stop there: Do not take the faucet apart if water still runs. Use the main shutoff only if you know where it is and it turns easily.
- Plug the drain: A sink stopper or towel prevents tiny screws from disappearing down the drain.
- Take a photo before each part comes off: This gives you a simple map for reassembly and helps at the hardware store if you need a matching part.
- Remove the handle: Look for a small screw under a cap or on the side of the handle. Many modern faucets use an Allen screw.
- Remove the retaining nut or clip: A retaining nut or clip holds the cartridge or stem in place. Keep it in your parts container.
- Pull out the cartridge or stem: Move gently and straight upward. If it is stuck, avoid twisting hard because old plastic cartridges can snap.
- Inspect the washer, O-rings, and cartridge body: Look for cracks, flat spots, swelling, grit, or dark grooves where water has been cutting past the seal.
- Match the part exactly: Bring the old part to the store or use the faucet brand and model number. A cartridge that looks close may still leak if it is not the right fit.
- Clean the faucet body before reinstalling: Wipe away grit and mineral deposits with a cloth. An old toothbrush can help around the valve opening.
- Grease rubber seals lightly and reassemble: Use a thin coat of plumber’s grease on O-rings only. Do not over-tighten the retaining nut.
- Turn water back on slowly and test: Open the shutoff valves a quarter turn at a time. Run hot and cold water, then watch the spout, handle, base, and cabinet for two full minutes.

Match the Repair to Your Faucet Type
A lasting leaky faucet repair depends on the faucet style. The wrong part or repair method is the main reason a drip returns a week later.
| Faucet type | How to recognise it | Common failing part | Best repair approach |
|---|---|---|---|
| Compression faucet | Separate hot and cold handles that tighten down | Rubber washer or valve seat | Replace washer and inspect seat |
| Cartridge faucet | One or two handles with smooth movement | Cartridge or O-rings | Replace cartridge with exact match |
| Ceramic disc faucet | Single lever, often newer, firm movement | Ceramic disc cartridge or seals | Replace disc cartridge or seal kit |
| Ball faucet | Single handle that moves over a rounded cap | Ball assembly, springs, seats | Replace full repair kit |
Compression faucets are common in older fixtures. They drip when the rubber washer gets flattened or the valve seat becomes rough. If you replace only the washer but the metal seat is pitted, the drip may come back.
Cartridge faucets are common in newer kitchens and bathrooms. If a cartridge is stiff, cracked, or scored, replacing the full cartridge is usually better than trying to patch one seal.

Kingston Checks Before You Force a Stuck Faucet
Some local homes need extra care before DIY repair. Older Barriefield homes and older Portsmouth Village properties can have galvanised supply piping. Galvanised pipe is older steel pipe coated with zinc, and it can corrode from the inside over time.
If a shutoff valve feels frozen, do not force it with pliers. A broken shutoff can turn a dripping faucet into an active leak under the cabinet.
Kingston municipal water is often very hard, commonly around 200 to 350 mg/L as calcium carbonate, and that mineral buildup can make cartridges sticky or shorten the life of small rubber seals. Clean visible grit from the faucet body before installing new parts so the new seal has a smooth surface.
Homes in Kingscourt and nearby central areas may also have aging pressure reducing valves. A pressure reducing valve, often called a PRV, is a device that lowers incoming water pressure to a safer level for fixtures. If water pressure is too high, faucet seals, toilet fill valves, and supply lines can wear out faster.
You may also notice more fixture trouble after winter. Freeze-thaw stress can affect outdoor taps and nearby shutoffs, especially if hoses were left connected. If your issue is outside, start with this guide on outdoor faucet leaks after winter.
When DIY Leaky Faucet Repair Is Not Enough
Most faucet drips are small, but a few warning signs mean it is time to stop. The goal is not to scare you. It is to protect your cabinet, flooring, and walls from a preventable leak.
Call a licensed plumber if the faucet still drips after an exact cartridge or washer replacement, the shutoff valves do not close fully, the faucet body is cracked, water appears under the sink, or the fixture moves on the countertop. You should also stop if a cartridge snaps during removal or if you see corrosion around copper, PEX, or galvanised connections.
A quick drip can also point to a bigger issue if multiple fixtures are acting up. For example, repeated leaks plus changing pressure can suggest a pressure problem. Repeated wet spots under cabinets can point to a connection issue, not just a faucet issue.
Homeowners in Rideau Heights often ask whether it is worth repairing an older faucet or replacing it. If the faucet is a quality fixture and parts are available, repair is usually sensible. If the finish is failing, the body is loose, or parts are discontinued, replacement may save labour and future frustration.
Frequently Asked Questions
Can I fix a leaky faucet without turning off the main water supply? Yes, if the hot and cold shutoff valves under the sink work properly. If they do not stop water fully, do not disassemble the faucet until the water can be safely isolated.
How do I know if I need a washer or a cartridge? Two-handle compression faucets usually use washers. Many newer single-handle faucets use cartridges, which are internal valve units that should be replaced with an exact match.
Why did my faucet start dripping again after repair? The most common causes are the wrong replacement part, a damaged valve seat, mineral grit left inside the faucet body, or over-tightening during reassembly.
Is a dripping faucet an emergency? A slow drip from the spout is usually not an emergency, but it should still be repaired to avoid water waste. Water under the sink, a failed shutoff, or a leak near electrical components should be handled promptly.
A Drip-Free Faucet Starts With the Right Diagnosis
A faucet drip is usually a simple problem when you match the repair to the symptom. First, find where the water is showing up. Then shut off the water safely, protect the drain, remove the handle carefully, and replace the exact worn part rather than guessing.
